AUTOMATIC GATE.

SPECIFICATION forming part of Letters Patent No. 271,963, dated February 6, 1883,

Application filed October 3, 1882. (No model.)

State of Ohio, have invented certain new and useful Improvements in Automatic Gates, of

. which thefollowingis a specification, reference being had therein to the accompanying drawings.

My invention relates to swingin'ggates; and it consists in the construction and arrangementof its several parts, as will be hereinafter fully set forth, and pointed out in the claims. In the drawings, Figure l is a general per-. spective view; Fig. 2,arear elevation with the post broken of, showing an elevation of the hinge-post of the gate; Fig. 3, a perspective from the bottom side of the lower gate-hinge; Fig. 4, a perspective of the crank; Fig. 5, a perspective of the latch; Fig. 6, a bottom plan of the lower hinge, and Fig. 7 a perspective of the crank in posit-ion.

' A is the main sill, and extending at right angles from the end upon which the gate turns are the detachable supplemental sills A. They are held in place by the bar a, one end of which is secured to one of the sills A, and

passes over bolts or pins or in the end of the sill A and side of the opposite sill A, as shown clearly in Fig. 2.

Secured vertically to each end of the sill A are the latch-post A and the hinge-post A The hinge-post is provided uponits upper portion with a hook, to which is pivoted the gate, and upon its lower portion with a plate, B, having a horizontal projection, b, in which is cut a semicircular slot, 1), as shown. The lower portion of the plate is recessed at 11*.

The turning post O of the gate is provided upon its upper portion with a plate, 0, having cut through it +-shaped slots 0, by means of which it is attached to the post and rendered capable of proper adjustment, as the gate shrinks or the post-settles down, and projecting from its central portion is an eyeplate, which fits over the hook in the hinge-post.

Attached to the turning post, below the plate 0, is a rod, of, which extends downwardly parallel with the post, slightly separated from it, and passes through the semicir- An oflsetprojects from the lower portion of the gates and engages with therod tions are the rods Which connect the gate swing ing with the actuating mechanism The actuating mechanism is situated upon the supplemental sills A, which are suitably enlarged and recessed to accommodate said mechanism.

Dis the crank, one end of which is bent horizontally for a short distance, and is journaled to the sill at d. The other and is also bent horizontally and is journaled to the sill, and projects into a suitable recess, (1, as shown.

.Secured to the long end of the crank and operating in the recess is the actuating-lever (1 having pivoted in its end a button or guide,

(F, to one end of which is secured the chain or rod which operates the gate. The outer end is bent over so as to bear against the top edge of the lever 01 and cause the guide to draw the chain to its full length when the crank is turned toward the gate, and turn upon its pivot and draw the chain only enough to bring the gate to a vertical position when the crank is turned away from the gate. Also secured to the same end of the crank is the hinged elevating-lever 61 It is pivoted to the weight d so that when the crank is turned down by the carriage-wheel the weight is lifted, and after the wheel has passed over it it drops back, causing the crank to turn up sufficiently to draw the operating rod or chain taut. A post is set up in front of the recess to prevent the wheel running into it, and a recessed guidepost, in which travels the chain. The rods 0 extend from the trips 0 to the guidesd as shown. They are in two parts, the ends of each being flattened, corrugated, and clamped together, with capability of being lengthened and shortened, as described.

The latch-post A is provided with a latch, E, and the swinging-post of the gate with a catch-pin, e, which engages with the latch.

The latch consists of a plate, 0, provided upon its lower end with a projection, 0 the top side of which has a central depression and bevels toward the edges, as shown in Fig. 5. Pivoted to the plate are double-acting pawls e having curved lips, which meet and form an open space between them for the reception of the pin 6. Above the pawls are placed pins 0"", which limit their throw.

In the operation of the gate the normal position of the operatingcranks is vertical. Upon the approach of a carriage the front wheel strikes the crank, which is turned down horizontally toward the gate, the lever d depressed, actuating rod or chain 0, drawn upon thetrip c lifts the lugs on the lock-plate 0 out of the recess, and the rod 0 is then drawn over to the side of the semicircular slot 1) from which the carriage is approaching. This action throws the turning postof the gate outof avertical line and elevates the swinging end. The latch-pin e is lifted out of the pawls e and the gate swings open in the opposite direction to that from which the carriage is approaching. After the carriage has passed through, the crank on the opposite side is turned down away'from the gate by the wheel, which operation causes the guide (1 to turn on its pivot and draw the chain only sufficient to bring the rod and the gate equidistant between the ends of the slot 11. The gate then swings between the posts and the latch-pin 6 passes under one of the pawls 6 is stopped by the outer one, and the gate, is there held securely between the posts.

It is seen that the only way to release the gate is by raising the pin out of the pawls,

which can only be done by turning down one of the cranks, whereby the swinging post of the gate is elevated and the pin lifted out of the pawls.

What I claim is 1. The combination, in a gate,'of a hingeplate secured to the hinge-post, formed with a slotted and curved projection, and recessed below said projection, with the gate having a rod secured to its pivot-post, said rod passing through the slot in the hinge-plate projection, and having alock-plate secured to its lower end, said plate being formed with lugs which enter the hinge-plate recess, and further providedwith pivoted trips which bear against the edges of said recess, and adapted'to release the lugs and lock-plate when drawn upon, as shown and described.

2. The laterally-acting gate-hinge, formed of the combination of a plate secured to the hinge-post, said plate having a curved and slotted projection and a recessed lower por-, tion, with a rod secured to the turning post of the gate, extending downwardly through the slot parallel with the gate, said rod having secured to its lower end a lock-plate having lugs which enter the recess in the hinge-plate, and trips to draw said lugs out of the recess, all arranged to operate substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
